Repeat Steps 2 through Step 4 for each LC and SP listed in the show platform

command output you 

obtained in Step 1.

Verify system stability by issuing the commands described in 

Once a software upgrade or downgrade is complete, you can clear space on a disk by removing any 
inactive packages that are not needed any more. Use the following procedure to remove unnecessary 
inactive packages:

Enter the admin command to enter admin EXEC mode.

RP/0/RP0/CPU0:router# admin

In admin EXEC mode, type the show install inactive brief command to obtain a list of inactive packages 
on the router, and note the names of packages that are not needed, as shown in the following example:

RP/0/RP0/CPU0:router(admin)# show install inactive brief

In admin EXEC mode, type the install remove disk0:package sync

 

command to remove any 

unnecessary packages, as shown in the following example:

RP/0/RP0/CPU0:router(admin)# install remove disk0:package sync

The sync keyword prevents the user from issuing any other commands while the installation is 
in process.

Multiple packages can be removed at the same time by specifying the disk0:package keyword 
argument once for each package, as shown in the following example:

RP/0/RP0/CPU0:router(admin)# install remove disk0:package1 disk0:package2 
disk0:package3 sync
